Similar to cock blocking or vagina blocking, bottle blocking is when you cock block your self. This occurs when one ingests wayyy to much alcohol, brings home a female or male, takes them to the bed room, and proceeds to pass out rather than fornicate.

-Dude did you end up getting with whats-her-face last night??
+NO! I totally got bottle blocked!! FUCK!
-Toats dude that blows..
